checked and it works, all test cases that pass without XCache now pass
with XCache too. i'll commit after your commit in ZendEngine

thanks

Hello Dmitry,

please don't apply. The patch looks rather rough and untested (see below).
Also I really disagree to making the engine even more complex and adding
even more different behavior ways. That way we just introduce more errors
as we cannot test the engine in all its modes. We simply do not have the
infrastructure for that. And that means we will add even more bugs.

Further more I am missgin a description what you really do here and why we
need to do that. Ok Opcode caches have issues but so far all attempts to do
somethign about that have been blocked. Now this one apparently has a new
option. But as far as I can tell it simply allows to change the compiler to
an opcode friendly order. If that is all what it does than we should simply
drop all the options and do it anyway without flags.

unnoticed.

Why rename this variable? It still is an exetended information in the
compiler globals. It's full name would be compiler_globals_extended_info'
versus 'compiler_globals_compiler_options'.

And this does also not work.

The reason is that you did not update the table that allows those
additions. Given that fact I doubt that you tested what you did and hence
this is just a quick shot at something I fail to get.
